Indexable Insert Drills Upgraded

Developments to the Perfomax indexable insert drills include a changed helix for improved productivity and chip evacuation; a refined core for improved strength and stability; and an improved drill point to increase tool life and achieve better tolerances. Additionally, a new coated lathe drill (SD572), and coated large diameter drill (SD542) that incorporates a helix flute and a range of 2.250" to 3.500" have also been developed. This generation of Perfomax drills has offered 50% higher tool life, 47% increased productivity, lower noise levels, and greater chip control due to better chip breaking.

Perfomax drills, featuring an optimized chip flute design, low friction coated drill body and strong inserts offer excellent productivity. This allows users to increase productivity and reduce total cost by boosting speeds and feeds, avoiding common problems of deflection, poor tool life and quality, even with long lengths and deep hole drilling applications. Unlike other indexable insert drills, all Perfomax drills use square inserts to provide the distinct advantage of a strong 90° corner and the economy of four cutting edges.

Perfomax is available in a large range of user-friendly drill diameters (0.59" to 3.50") and lengths of up to 5xD in certain sizes. Inserts are available in a wide range of geometries. Perfomax uses different inserts in periphery and center insert pockets providing balance of cutting forces and highest cutting data.
